Application September so, 1935, Serial No. 42,912 3 Claims. (01. 250-33) the use of unsightly wires strung around a room;

A further object of the invention is to proas hereinafter set forth, a portable radio antennaunit having its receiver element concealed and with the unit of a form capable of being disposed flatwise upon the fioor of a room; supported upon an article of furniture and connected to a table covering. I

Further objects of the invention are to provide, in a manner as hereinafter set forth, a radio antenna unit which is simple in its construction and arrangement, strong, durable, compact,in the form of a drusget, conveniently transported to the position desired, attractive in appearance, readily installed with respect to the antenna post of a radio receiving set, thoroughly efllcient in the use intended'thereby and inexpensive to manufacture.

With the foregoing and other objects which may hereinafter appear, the invention consists of the novel construction, combination and arrangement of parts as will be more specifically referred to and as are illustrated in the'accompanying drawings wherein are shownembodiments of the invention, but it is to be understood that changes, variations and modifications may be resorted to which fall within the scope of the invention as claimed.

In the drawings:

Figure 1 is a fragmentary view in perspective of the unit,

Figure 2 is a perspective view of the unit broken away at its front face, 1

Figure 3 is alongitudinal view of the unit,

Figure 4 is a perspective view of the unit partly extended into a covering for an article of furniture, I

Figure 5 is a fragmentary view in elevation of a modified form of receiver forming an element of the unit, Figure 6 is a perspective view of a modified form of antenna unit inverted, and I Figure 7 is a sectional detail of the shown in Figure 6.

With reference to Figures 1, 2 and -3; the unit generally indicated at ii includes a set of spaced parallel narrow, thin supports of like and the desired length. The outer end supports of said set are indicated at structure set and the bends of the I The stretches and bends cured by any suitable means to the supports and to the stretches and I 9, l0 and-the intermediate supports at H. I Each support wil1-have its ends l2 rounded. The supports are arranged in equidistant spaced relation and are formed of any suitable electrical non-conducting material. Ar-. ranged against corresponding faces of the sup- I ports is a receiver element. generally indicated at l3 and which is formed from a length of any suitable wire. Thelatter may or may not be insulated and is shown as being non-insulated from end to end thereof. The element l3 consists of a, series of equidistant spaced straight parallel I stretches and two sets of spaced curved bends together and disposed connecting the stretches at right angles to the ends of the stretches. The outer stretches of the element l 3 are indicated at l4, IS. The intermediate stretches of. the element l3 are designated IS. The bends of one l4, l5 and i6 extend from the support 9 to the. support Ill and are disposed transversely of the supports II.- The bends I! are arranged on support 8. The bends I I8 are arranged on the support-l0. The free end of stretch it is secured tosn end of support 9 by an adhesive tape l8.

these latter, when secured bends, act as a bracing means for element l3, a means-for maintaining thestretches in spaced relation and. a means for retaining the bends of each set in spaced relation. The stretch l5 has that end thereof which is not connected to a bend disposed at the outer side edge of support Ill.

The unit 8' includes a lead element ii! for connection to'the antenna post, not shown, of a radio receiving set. The element I9 forms a continuation of the ment IS. The element l9. extends from the stretch I5, is insulated throughout, carries a plug 20 and is of the length desired.

wire which provides the'ele- I other set of element l3 are designated l1, l8 respectively. The stretches of element l3 are se The unit 8 includes an enclosing cover element 2| for concealing the supports and element l3. The element 2| is formed of two sections 22, 23, preferably of electrical non-conducting material. The sections 22, 23 are secured together in superimposed relation, thereof, by rows of stitching at the marginal portions 24 and which provides a closed pocket 25 in which are arranged the supports and element l3. The element I9 the latter. The bodies of the sections 22, 23 may ing the unit 8 attractive inappearance.

With reference to- Figure 4 there is shown a extends from element 2i between the sections of a set of spaced parallel cover 26 for an article of furniture. The cover 26 has secured to one face thereof a web of fabric 21 to provide, in connection with the body of the cover 23, a pocket 23 for receiving the unit length of any suitable wire. The latter may or may not be insulated and is'shown as being noninsulated throughout". The element 23 is formed of a series of coils and with the coils progressively increasing in length from the inner to the outer coil. The inner and outer end coils of element 23 are indicated at 30, 3| respectively and the intermediate coils at 32. The coils are arranged in I equidistant spaced relation. The element 23 also includes a straight stretch 33 which merges at its inner end into the outer end of the outer coil 3|. There is associated with the element 29 narrow thin supports of like and the desired length. The outer end"sup- "ports of said set are indicated at 34, 34 and the intermediate supports at 36. Each support will have its ends rounded. The supports are arranged in equidistant spaced relation and formed of any suitable electrical non-conducting material. The coils 33, 3|, 32 and stretch 33 of the element 29 extend across corresponding faces of the supports 34, 33 and 34. The coils 30, 3!, 32

andstretch 33 are secured by any suitable meansagainst the said corresponding faces of the supports. The inner end of the'inner coil 33 of the body part of element 29 is anchored to the central support of the intermediate supports 33 by an adhesive tape 31. The outer end of the stretch 33 of the element 23 is flush with the outer side edge of the support 34. The outer coil- 3| of element. 29 extends upon the outer end-supports 34, 35 and the intermediate supports 38. Extend ing from the outerend of the stretch 33 is a lead element "constructed in the same manner and for a like purpose as the element I I3.- The element 29 and supports 34, 33 and 34 are adapted to be housed and secured in the cover element 23.

channels 4 l With reference to Figures 6 and 7, a modified construction of antenna unit is illustrated and which consists of a rug.34 of the form which has its bottom face provided transversely thereof with spaced parallel ribs 40 forming spacedparallel 4| which are spaced from each other Bya plurality of the other of said channels are the stretches 42 of a receiver element 43 of theform shown in Figure 1. The, stretches 42 correspond in length to that of channels 4|. The bends 44 of the elements 43 are arranged at the side edges 45 of the body of the rug 33. The stretches '42 are secured in the channels 4| by the stitchings 46 which form parts of the body of the rug. Extended from elements 43 is a lead element 41 of a construction similar to and for the same p rpose as the element 43.
